Table changes in database.

Hi,
I created few Subject Areas. One of the table was modified in the database. They added an additional column to the table and doing some index changes. Do I have to delete the existing table and re-import the modifed table into the rpd and again join the table with other tables as required? What is the most efficient way to do this?

If its just one extra column, id add it manually in the table properties, check the changes in, do a 'show data' from right click to check everything is OK.
There is also 'update physical layer' option in the menu items in the Admin tool if there are many.
I wouldnt delete the table as you will lose the links through to the Logical table sources and any columns mapped, a right pain when thats the only option so try not to !.
Always a good idea to use Aliases, as you can swap the source table for the alias over to a temp table in this situation and refresh the 'real' table, then swap the alias back, thus keeping all your hard work mapping the BMM intact.
Hope this helps,
Rgrds

Table changes in database are not captured in ODI model level

Hi All,
Can any one help me how to fix the bug in ODI.
Table changes in database are not captured in ODI model level.
Thanks in advance

I created the interface which is running successfully.
Now i did some changes in target table(data base level).
I reversed the updated table in model section. Till here its ok
The table which is updated in the model section is not automatically updated in the interface.
I have to drop the existed datastore in the interface and and re do the entire process of bringing the updated datastore, mapping,etc..
Please tell the any alternate way.

Synchronize table changes from Database to ODI

HI all,
which is the best approach to synchronize database changes into ODI.
Is there any way of automate it?
FOr instance, if we have a datastore as target and some data types are changes in the database, re-reverse will not apply these changes ...
Thanks

Tracking changes in database tables

Hi,
I have a couple of database tables on which more than 20 people work each day, throughout the day. I have the requirement of tracking each and every change made on any row of the table.
For example, If a user accesses a specific row, and updates, or deletes it, i need to keep a track of the userid of the user who did it.
Is that possible?

Hi Bharat,
If they are Z tables i.e custom tables then you can incorporate two more fields userid and time. Now goto Table maintanence generator through SE11.Then select Environment->Modification->events. Now in the next screen select F4 for first field to select the event i.e when your code has to be executed.Then give a new form name and click on editor icon. write your code here. When ever a user changes any record his name will be included in user id and sy-uzeit in time field. This way you can track who has changed the record. Other option is activating table changes recording by selecting "LogChanges " check box in technical settings of table.and profile parameter rec/client should also be switched on. Then you can see your table changes in SCU3 transaction. Hope this helps.

Kalyan.

Help with creating a sql file that will capture any database table changes.

We are in the process of creating DROP/Create tables, and using exp/imp data into the tables (the data is in flat files).
Our client is bit curious to work with. They do the alterations to their database (change the layout, change the datatype, drops tables) without our knowing. This has created a hell lot of issues with us.
Is there a way that we can create a sql script which can capture any table changes on the database, so that when the client trys to execute imp batch file, the sql file should first check to see if any changes are made. If made, then it should stop execution and give an error message.
Any help/suggestions would be highly appreciable.
Thanks,

Just to clarify...
1. DDL commands are like CREATE, DROP, ALTER. (These are different than DML commands - INSERT, UPDATE, DELETE).
2. The DDL trigger is created at the database level, not on each table. You only need one DDL trigger.
3. You can choose the DDL commands for which you want the trigger to fire (probably, you'll want CREATE, DROP, ALTER, at a minimum).
4. The DDL trigger only fires when one of these DDL commands is run.
Whether you have 50 tables or 50,000 tables is not significant to performance in this context.
What's signficant is how often you'll be executing the DDL commands on which the trigger is set to fire and whether the DDL commands execute in acceptable time with the trigger in place.

Table in the Database will be changed, what is impact

Hi, I'm new to the Forum.
We have a multiple reports build in the multiple Business arias, One of the Tables in the Database will be changed. My question is what is the best way to use EUL5 to see what impact it will make. I will appreciate any advise.

When you say one of the tables in the database will be changed, do you mean columns will be added, or are some columns going away, column names changing, tablename changing or what?
If the table is just getting some new columns added, then no problem. Your existing reports will still be fine and when you perform a refresh on the business area where the folder is pointing to your table, it will just pick up the new items.
If columns are going away, then your reports will get an error if they refer to that column name via the folder. You can do a kludge to cover this for the short term. In the folder in Admin, you can add a calculation with the exact same name as the column that's going away. Then - if it's a character - put in some kind of striking phrase like 'Russ Was Here'. Then when the existing reports are run, you'll see the phrase and know you just have to delete it from the report. Once all gone from all reports - you can delete the condition from the folder.
Hopefully you can see the reliance on the Discoverer folder having to have a non-changing table. The easier thing to do for the future - is to create a database view that points to the table. Then if the table changes in ANY way (well, except from being deleted altogether with no replacement table), you can always fix the view to return proper data and as your Disco folder is pointing to the view, nothing changes.
Hey this is what NoetixViews does, what BIS view do, etc. - it's IMHO the best way to go for future development.

Track of table changes in a database

how to keep track of table changes in a database.
Some records have been deleleted, is there away of seeing that change.

basically, if you havn't already set up a mechanism to track these sorts of changes, they are already lost.
there are a number of things you can do. one method that we use is a trigger on the table to insert a record into an audit table for every row that gets changed or deleted.
oracle has some other built in auditing tools that I'm not familiar with though.

Listeneing to a Change Table in a Database

Dear Java Coders,
I would like to code a universal database synchronizer, I'm stuck at planning the project.
My software is server-side; configuration files are in XML and Databases are universally configured via the configuration files. Now my only "Newbie" difficulty I see, is a Listener for Database Data Change. For eg.
Database A : id = 01 < ==| Change Listener |== > Database B : id =02
Can someone please advise me on this ?

Hi,
you can write your own Listener-methods.
Create an interface and implement in Database B this interface, in Database A implement a second interface that adds the Database B Listener to an array. If Database A will be changed call the interfaceDatabaseB-method.
This should work.
Sabine
Listener: Database B implements ListenerInterface
ListenerInterface
=> method callListener()
Caller : Database A implements ListenerCallerInterface
ListenerCallerInterface
=> method addListener

Data in the table changes when multiple users try to submit data

I have a dynamic table. The table is created in the wdDoModifyView. The user can load data into the table from an excel file. So I have a "Load" button that loads the data from the selected excel file to the table. I also have a "Submit" button. This "Submit" button converts the data to an xml file and make a call to an oracle stored procedure for validation check. If there's an error it will be returned and displayed to the user. If none, a summary of data for posting will be displayed to the user. If the data is correct and the user hit the ok button, the same data will be return to oracle sp for loading in the table.
The problem we encountered is when multiple users are loading and submitting at the same time, the data displayed in the dynamic tables changes after clicking the ok button. It is as if, the table displays the data being loaded by other user.
This is an error that is difficult to recreate. This doesn't happen all the time. I hope you somebody could enlighten me why this is happening. I'm not sure if it has something to do with multithreading or session.
Edited by: Marlyn Agco on Apr 14, 2009 3:57 PM

Hi Armin,
Did you mean storing view instances in static references and accessing them outside the wdDoModifyView is not a good idea? In wdDoInit the nodes are dynamically created according to the xml file being returned by the database. This node is stored in a static variable which is also used in wdDoModifyView to create the dynamic table.
What do you suggest? We're still encountering same issue when multiple users are uploading data.

Is there a way to create "temporary" tables in SAP database?

Hello,
Is there a way to create temporary tables in ABAP?
Here is our scenario:
1. Invoke a custom RFC that creates a temporary table and returns the name of the table.
2. Invoke another custom RFC and pass this table name as parameter. This RFC internally does some INNER JOIN with the temporary table.
3. Invoke the third RFC to delete the temporary table.
Note that the name of the table cannot be static. We have many users using our application simultaneously and connecting to the SAP server.
I would appreciate it if you could point me in the right direction.
Thank you in advance for your help.

I just ran into a similar issue. While only calling the select statement 2 times, each time had so many entries in the 'for all entries' list, that the compiler converted this into about 700 calls to the select. Now since the select joined three real tables on the database, the trace shows this one select as being the slowest item in this application.
I think that happened because 'for all entries' gets converted to an 'IN' clause, and then the total number of characters in any SQL statement has an upper limit. So the compiler must make the select statement over and over until it covers all entries in the 'for all entries' list. Is that correct?
Since every database I ever saw has the concept of db temporary tables, I have used db temp tables many times for this sort of thing.
The ABAP compiler could determine that more than one IN statement will be need, then use an alternate: write all the FOR ALL ENTRIES to a db temp table, then join on the db temp table, then drop db temp table. Since the compiler does this sort of thing, no application code needs change to get the speed boost.

I don't have the option to create a new table in my database

Hi, I have SQL 2014, for some reason, a few weeks ago I was able to create a new table for my databases, now, I don't have the option to do so, all I get when I right click on tables is "Tables..." instead of "New Table", when I select
"Tables..." it allows me to write my codes but it doesn't save except in a text files witch doesn't want to open when I want to resume my work.
Is there any option in SQL to activate the "New Table" by right clicking on Tables? I have all the rights and permissions available to my use as it's my computer and my own server.
To fix the issue I tried
-Re-installing SQL
-Changed for 4 different versions
-Allowing more than necessary permissions
-Making it public to use (it's only to test it, anyway, I'm in the learning phase)
Any kind of help or advice will be welcome and much appreciated.
Thank you!

I don't know the reason why you are experiencing this, so what I am describing below are just some steps that you can take to diagnose the problem if it is related to a permissions issue.
1. If you are not already on the computer where SQL Server is installed, login on that box and launch SQL Server Management Studio and run it as Administrator.
2. Connect to the Server and open up the object explorer and expand the Security node that is directly under the Sever tab.
3. Under logins, find your login, right-click properties and see what kind of server level permissions you have, and which databases you are mapped to and what kind of permissions you have on those.
It may just be that this is not related to permissions at all, but I can't think of what that would be. To test whether it is a SSMS GUI problem or not, open up a query window and select a database on which you think you have permissions to create tables.
Then create a test table using T-SQL, for example:
create table dbo.MyTestTable( col1 int);

How to change the database in a business area

Hello All,
I am trying to figure out a way to change the database that a business area connects to. When I created the business area I selected to look at tables from the default database. Now I need to change that setting to connect to a different database. The tables are exactly the same on both databases. I just need to change the database that the business area looks at.
Is there a simple way of accomplishing this? I want to avoid having to recreate the business area.
Thank you very much in advanced for your help with this matter.

How to mirroring/replicating a table from one database to another database?

I am having a table in 10g Database.
I want to mirror this table in 9i Database.
How to do this?

1) Just to clarify, it is quite possible to use Streams between a 9i and 10g database (note for future reference that specifying actual database versions, i.e. 9.2.0.4 or 10.2.0.4 rather than marketing labels is generally helpful because there may be differences between different 9i and 10g releases)
2) Are you setting up one-way replication? Or will changes be made on both databases, implying the need for multi-master replication?
3) Why doesn't the table have a primary key? Could you declare a primary key? If not, you'd have to use the ROWID (i.e. specify WITH ROWID when creating the materialized view log and the materialized view) which tends to cause maintenance issues down the line. It really doesn't make sense to replicate a table without a primary key-- it really doesn't make sense to design a table without a primary key the vast majority of the time.

How to reflect db changes - Verify Database doesn't seem to work

I have changed a database (MS SQL Server) column from varchar 255 to varchar 1000, but the designer doesn't pick up the change.
I read that db changes can be picked up by using 'Verify Database' feature. It doesn't seem to work for us though. Is there any configuration to turn on for the feature to work properly or any work-around to refresh the database changes?
We are making the database connection using JDBC (JNDI) option since the report is being used in a Java web application.
Any comments or insights will be very much appreciated!

Hi Wallie,
Thank you very much for your reply! Here are the answers to your questions.
Are you able to create a new report off the modified database?
==> Yes.
Do new reports see the changes made to the database?
==> No.
Are the reports connecting directly to the database table, or is it a stored procedure, business view, universe being used?
==> Through a business view.
By the way, after trying so many things, I was able to figure out the reason. Since the report is using a view, not directly the table, the view itself had to be recompiled to reflect the table changes so that the view could pass the changes to the report. It was a very good thing to know. Your last question could have been a very helpful insight for this issue! Thank you so much again!

Facing problem while changing the database at runtime

hi everyone,
Before posting this thread, i have gone through the various posts addressing the problem....but still iam unable to get the solution for this problem.
The report has been generated in one system, so the database properties (connection string....) are hardcoded in the report file...
Now when iam trying to change the database, it is still connecting to the system where the report file was created.
I have tried the changeDatasource() method, but it didnot worked....
here is the code for changeDatasource() method
public static void changeDataSource(ReportClientDocument clientDoc,
                String reportName, String tableName,
                String username, String password, String connectionURL,
                String driverName,String jndiName) throws ReportSDKException {
        PropertyBag propertyBag = null;

Also i tried with replaceConnection() method...........it displayed the report, but with not column names and data
need help regarding.......
Edited by: abhishek.c1984 on Jun 25, 2009 10:02 AM

In the report i have two tables.............so before changing the database properties for each table iam printing their names.
The names are dispalyed correctly.......but once i set the table location...i.e through the following method..
clientDoc.getDatabaseController().setTableLocation(tables.getTable(i),newTable);
every time i can see only one table i.e. properties are set for the first table ........and each time the properties are being set for the first table only.....i dont no what is happening to the rest of the tables..
I have posted the method in the above post.....can any one please trace out the problem
Note: when i comment the following code, i can see all the tables
clientDoc.getDatabaseController().setTableLocation(tables.getTable(i),newTable);
when i uncomment it, i can see only first table repeating every time...
